In ordering tools, and in correspond- 
ence, we strongly urge the use of our 
catalog numbers. This is as important 
to the customer as it is to us, and will 
often prevent misunderstandings, delays 
and annoyances. 

We make many special tools of varying 
styles and dimensions and will gladly 
submit prices upon receipt of specifica- 
tions. In the appendix we give sketches 
and suggestions to be followed when 
ordering special goods. 

Catalog numbers of High Speed Steel 
Tools are the same as those of Carbon 
Steel plus 1000.

ANDREW'S PATENT DRILL SOCKETS 

FOR MORSE TAPER SHANK DRILLS 

No. 225 




These Sockets are fitted with a Key sliding in a radial slot in the 
holding head. The Key bears upon the inclined seat in the shank of 
the drill and is forced to its seat by a cap fitting over the holding head. 
Turning the cap by the hand in one direction holds the drill firmly in 
place, while turning it in the opposite direction releases its grip so that 
the drill can be easily removed. 

For illustration of drill with Andrew's shank see page 12.

Short Shank Sockets are for use with drills on which the 
original tangs have been broken, the shanks reduced in length 
and fitted with thicker and wider tangs, thus insuring a strong 
drive. Gauges for fitting drills with broken tangs to Short 
Shank Sockets can be furnished on receipt of order, see page 6. 

Shank is Morse Standard Taper. Hole only is for Short Shanks.

STETSON DRILL CHUCK 




This chuck is strong and of heavy construction. The jaws are con- 
trolled by separate drivers, and are guided in that part of the chuck 
which is attached to the driving spindle. This arrangement gives 
increased strength to the chuck. 

The threaded and working parts of the Chuck are covered, and 
thereby protected from injury and dirt.

MORSE TAPER SHANK DRILLS 

FITTING Andrew's socket 



The above cut represents the shank of the drill used in the Andrew's 
Socket. The drills are held in place by the key in the socket. As the 
groove extends the entire length of the shank, there is no difficulty in 
PLACING the shank in the proper position. 

The groove in the shank is deeper near the shoulder than at the outer 
end of the shank which prevents the drill from being pulled out of the 
socket as well as from turning in it. 

Drills having shanks milled or fitted in this way are furnished at 
regular No. 302 list. 

For illustrations of Andrew's Sockets, see page 3.

THREE-GROOVE DRILLS— morse taper shanks f 



It is considered advisable to use two drills when large holes are to be made in solid 
stock, first using a two-groove drill and following with a three or four-groove drill. 

A two-groove drill should not be used in cored holes or to follow another drill. 

The points of the three and four-groove drills show that they are not to be used for 
drilling solid stock but for enlarging a hole already made.

OIL HOLE DRILLS 



INCEPTION AND ADVANCE 




This method of conveying lubricants to the point of a drill or cutting tool was 
exhibited by the Morse Twist Drill & Machine Company at the World's Fair at 
Chicago in 1893, the drills then exhibited being duplicates of some made during the 
two previous years. The "American Machinist" and "Iron Age" in the year 1893 
illustrated and explained this style of tool. 

Various devices have been used to convey the lubricant to the points, the early 
methods providing for an inserted tube. The latest improvements, however, provide 
holes through the solid metal. 

All oil drills 2V^ inches and smaller in diameter have holes through the solid metal, 
while with sizes larger than 2]/2 inches it has been found advisable to mill the oil 
channels and cover them. These drills are not made smaller than H diameter except 
at customer's risk. Sizes ^ and smaller are furnished with one oil hole only. They 
can be furnished with two if especially ordered, but at customer's risk. 

Oil drills are illustrated and their manner of use fully explained on pages 77 to 86. 



Cups for Use in Oil Drills 






In ordering new cups give size of drill in which they are to be used.

WITH TAPER SHANKS 



These cuts are a reproduction on a small scale of drills which were actually made 
and used with eminent satisfaction, the proportion of the cuts to the drills being correct. 
The actual dimensions of the drills were, diameter 3^ inches, whole length 52 inches , 
length of shank 8 j^ inches.

The Drills are furnished with Straight 
or Taper Shanks, as desired. 

For Drills with Oil Holes of style 
shown below, see pages 80-86. 




'■'. In using the Hollow Drill the hole is first to be started by means of a short drill 
of the size of the hole desired, and drilled to a depth equal to the length of the body 
of the Hollow Drill afterwards to be employed. The body of the Hollow Drill acts 
as a stuffing, compelling the oil to follow the grooves and the chips to flow out through 
the hollow shank.

These drills have holes through the solid metal and have great advantages over any 
other drill devised for conveying lubricants as well as air to the point. When drilling 
cast iron, air is sometimes used for blowing out the chips and keeping the drill cool. 

♦These drills H and smaller are furnished with one oil hole only. They can be 
furnished with two if ordered, but at customer's risk. 

For information in regard to manner of use see pages 4, 78, 79.

♦These drills ^ and smaller are furnished with one oil hole only. They can be furnished 
with two if ordered, but at customer's risk. 

These drills have holes through the solid metal and have great advantages over any 
other drill devised for conveying lubricants as well as air to the point. When drilling | 
cast iron, air is sometimes used for blowing out the chips and keeping the drill cool. 

For information in regard to manner of use see page 78.

The above drills have a hole lengthwise through the shank connecting with the 
grooves of the drill. The shank can be threaded and fitted to a metal tube of such 
length as desired. Tubes are made to order and to fit any size of drill. When order- 
ing give diameter of drill and depth of hole to be drilled. 

The lubricant is conveyed to the point of the drill on the outside of tube, as illus- 
trated on page 78, while the hollow tube admits of the passage of oil and chips from 
the point. 

These drills are accurately ground on centers. 

In drilling crucible steel the best results are obtained by revolving the work at a 
speed equalling a periphery speed for the drill of 20 feet per minute and feeding at the 
rate of .0025 inch per revolution. Machinery steel will admit of increased revolution 
to 40 feet per minute, and a feed of .0035 inch per revolution. 

For information as to the use of this drill see page 78. 

32nd sizes not listed furnished at intermediate prices and 64th sizes at price of next 
larger 32nd size.

any size in line with an index mark , and by inverting the case the selected

TAPER MANDRELS WITH EXPANDING 
SLEEVES 




The entire Mandrel is hardened and the taper ground. The taper is such that it 
will hold the Sleeve and the work rigid. The Sleeve is of crucible steel, not hardened, 
and has several longitudinal slots, giving the Sleeve greater flexibility. One of the 
slots is cut through, allowing the Sleeve to expand or contract.

For Arbors fitting these Reamers see page 119. 

An Adjustment Socket Wrench and a Key are furnished without charge with each 
Reamer. 

Turning the Cam Bolt in the Shell by the slotted head moves all blades at once 
and all exactly alike, outward from the center. When the desired diameter is reached 
be sure all blades are firmly seated on Cam Boll before the Lock Nut is tightened. 

Nothing to get out of order. Only three parts besides blades. One movement 
operates all blades at once. One nut locks them. 

Exact adjustment is quickly made to any size within range without regrinding 
blades. See page 1G7. 

Reamers for Brass or Bronze require special clearance and are so furnished on 
request.

ADJUSTABLE SHELL REAMERS 




The cut shows the construction of our Patent Adjustable Shell Reamer. The 
wedge-shaped blades are held rigidly in slots by means of taper keys. 

The bottom of the slots is inclined to the axis of the reamer, and the size may be 
adjusted by first driving back the keys and turning the nut in the required direction. 
The keys should then be driven home to lock the blades. 

This style of Adjustable Shell Reamer is not made smaller than 1^ inches, but can 
be made solid as small as M inch, 

A Wrench furnished with each Reamer.

FORMED SAWS 




FOR SLITTING COPPER 

These saws are designed especially for the slitting 
or sawing of metals that are of a soft or tenacious 
character and are superior to the ordinary saw 
usually employed for this purpose. The teeth are 
formed and backed off the same as in all formed 
milling cutters, and are sharpened by grinding the 
face, thus retaining the outline of the saw. The 
sides of the saw are ground concave for clearance. 

These saws are made to order. 

Prices on application.

FEEDS AND SPEEDS 

Feeds and speeds vary considerably according to the materials used. We would 
recommend the following surface speeds as correct for most requirements, to be varied 
according to the work as seems necessary. With carbon steel cutters for brass 80 to 
100 feet per minute; for cast iron 40 to 60 feet per minute; for machinery steel 30 to 
40 feet per minute; for annealed tool steel 20 to 30 feet per minute. With High Speed 
Steel Cutter for brass 150 to 200 feet per minute; for cast iron 80 to 100 feet per minute; 
for machinery steel 80 to 100 feet per minute; for annealed tool steel 60 to 80 feet per 
minute. 

The number of revolutions per minute to get the required surface speeds will be 
found in tables on pages XXVIII and XXIX of the appendix.

The diametral pitch of a gear is the number of teeth to each inch of its 
pitch diameter. 

The circular pitch is the distance from the center of one tooth to the 
center of the next tooth, measured along the pitch circle. 



212 MORSE TWIST DRILL AND MACHINE COMPANY 



INVOLUTE CUTTERS 

FOR THE TEETH OF GEAR WHEELS 

These cutters can be sharpened by grinding the faces of the teeth. 
To preserve the form of the cutter care must be used in grinding to keep 
the face of each tooth radial. 

To cut a set of interchangeable wheels with theoretical accuracy, as 
many cutters would be required as there are different wheels in the set, 
for the reason that, strictly speaking, the shape of the teeth should 
vary with every change in the number of teeth in the wheels. As this 
change of form is slight and becomes less with each increase in the 
number of teeth, it has been found that a set of wheels ranging from 
a pinion of twelve teeth to a rack can be cut with sufficient accuracy 
for most purposes by the use of eight cutters, as follows : — 

No. 1 will cut wheels from 135 teeth to a rack. 

No. 2 will cut wheels from 55 teeth to 134 teeth. 

No. 3 will cut wheels from 35 teeth to 54 teeth. 

No. 4 will cut wheels from 26 teeth to 34 teeth. 

No. 5 will cut wheels from 21 teeth to 25 teeth. 

No. 6 will cut wheels from 17 teeth to 20 teeth. 

No. 7 will cut wheels from 14 teeth to 16 teeth. 
No. 8 will cut wheels from 12 teeth to 13 teeth. 

For work requiring still more accurate teeth a set of 15 range cutters 
for each pitch is often used, using half numbers for the intermediates as 
follows : 

No. 1 will cut wheels from 135 teeth to a rack. 

No. VA will cut wheels from 80 teeth to 139 teeth. 

No. 2 will cut wheels from 55 teeth to 79 teeth. 

No. 23^ will cut wheels from 42 teeth to 54 teeth. 

No. 3 will cut wheels from 35 teeth to 41 teeth. 

No. S}/2 will cut wheels from 30 teeth to 34 teeth. 

No. 4 will cut wheels from 26 teeth to 29 teeth. 

No. 43^ will cut wheels from 23 teeth to 25 teeth. 

No. 5 will cut wheels from 21 teeth to 22 teeth. 

No. 53^ will cut wheels from 19 teeth to 20 teeth. 

No. 6 will cut wheels from 17 teeth to 18 teeth. 

No. 63^ will cut wheels from 15 teeth to 16 teeth. 

No. 7 w^ill cut wheels of 14 teeth. 

No. 7J^ will cut wheels of 13 teeth. 

No. 8 will cut wheels of 12 teeth. 

Each cutter is marked with its number, also the diametral pitch and 
number of teeth for which it is adapted. In ordering, give number of 
cutter and diametral pitch required.

CUTTER CLEARANCE 

Correct clearance on cutters is important and should always be 
considered when a cutter is being sharpened. The cutting edge only 
should come in contact with the work and sufficient stock should be 
removed back from the cutting edge so that there is no scraping or 
dragging action.

CUTTERS FOR MITRE AND BEVEL GEARS 

Mitre Gears are Bevel Gears having the same number of teeth and 
whose center lines intersect at right angles. 

A pair of Mitre Gears can be cut with one cutter, but a pair of Bevel 
Gears that are not Mitres may require two cutters. 

Cutters for Bevel Gears are of similar form to those for spur gears 
except for thickness, which must be no greater than the space between 
the teeth of the gear at their inside ends. As usually made, cutters are 
thin enough to cut a gear whose tooth face is not longer than one-third 
the distance from the outer ends of the teeth to the point where the 
center Hues of the gears intersect. 

Eight cutters are made for each pitch. In cutting a Bevel Gear it is 
usually necessary to use a cutter of a shape adapted for a greater num- 
ber of teeth than the number of teeth in the gear to be cut. The 
number of cutter for each gear of a pair may be found as follows: First, 
find the center angle of the larger gear by dividing the number of teeth 
in same by the number of teeth in the smaller gear; the result will be 
the tangent of the center angle which may be found by reference to a 
table of tangents. The number of teeth in the larger gear divided by 
the cosine of this center angle will give the number of teeth for which a 
cutter should be selected to cut the larger gear. The number of teeth 
in the smaller gear divided by the sine of this same center angle will 
give the number of teeth for which a cutter should be selected to cut 
the smaller gear. In the case of Mitre Gears, this is equivalent to 
multiplying the number of teeth in one of the gears by 1.41 and selecting 
a cutter for the number of teeth indicated by the product. 

Example: To select a cutter for mitres of 40 T, multiply 40 by 1.41. 
The product 56.4 shows that a cutter of shape No. 2 for 55 to 134 T. is 
the one required. 

In ordering cutters for Bevel Gears, if the number of teeth in each 
gear, the pitch and length o^ face are given, also the angle of the shafts, 
we can select the proper cutters.

SERIAL HAND TAPS 



FOR USE IN STEEL OR OTHER TOUGH MATERIAL 



i 



TAPER PLUG BOTTOMING 



TAPER PLUG BOTTOMING 



These Taps are particularly adapted for use in tough steel, such as 
generally used in boiler and locomotive work. They are furnished in 
sets of three taps so designed that a proportionate amount of the metal 
is cut out by each succeeding tap. 

The No. 1 Tap roughs out the thread, the No. 2 being a Httle larger 
in pitch diameter cuts the thread a little fuller, and the No. 3 finishes 
the thread to full size. 

The advantages of these taps over other styles of hand taps are, that 
by their use the possibility of torn threads is practically eliminated, the 
life of the taps is greatly increased, and the power required to complete 
the tapping operation is materially lessened.

SPINDLE STAY-BOLT TAPS 

WITH THREADED SPINDLE 

These Taps are so constructed that the lead of the internal 
and external threads exactly coincides, which insures the 
tapping of a continuous thread in the two boiler sheets where 
the stay-bolt is to be located. The distance between the sheets 
may be anything within the limits of the length of the spindle. 

These Taps will be furnished in sizes of J^ to 13^ inches 
diameter, inclusive, as per list below, with the United States 
Standard form of thread, 12 to the inch. 

These Taps with V form of tliread are special. 

The length over all and the length of threads of these Taps 
is the same as our regular spindle stay-bolt taps, No. 1131, 
page 268. 

Sizes, lengths, and threads not hsted are subject to special 
prices. 

Spindles y6 inch diameter and 36 inches long will be fur- 
nished unless otherwise ordered. 

Each set consists of two taps and a spindle.

GRINDING 
TWIST DRILLS 

Few operations on 
tools in the shop are 
more frequently dis- 
appointing than the 
grinding or sharpening 
of drills. That the 
cutting edges have a 
proper and uniform 
angle with the longi- 
tudinal axis of the 
drill (see Fig. 6), hav- 
ing them of exactly 
equal length, and the 
lips of the drill well 
and sufficiently backed 
off or cleared, are 
points generally under- 
stood as requisite to 
the satisfactory per- 
formance of a drill, 
though not always at- 
tained. Practical sug- 
gestions for the grind- 
ing of drills have been 
published from time 
to time. We append 
in part from these, 
hoping they will be 
found useful. " If the 
clearance of a drill is 
insufficient or imper- 
fect it will not cut. 
When force is applied 
it resists the power of 
the drilling machine, 
and is crushed or split. 
It is well to start a 
drill, after grinding, by 
hand, observing the 
character of the chips, 
which should charac- 
terize a clean cutting 
tool. In wrought 
metal the chip^ will 
sometimes attain a 
length of several feet. 
Prof. Sweet suggests 
that the rear of the lip 
of a drill be removed, 
as shown by the cut. 
No. 1; this makes the 




VI 



MORSE TWIST DRILL AND MACHINE COMPANY 



GRINDING TWIST DRILLS— Continued 

cutting edge much like a flat drill. Drills properly made have their 
cutting edges straight when ground to a proper angle, which is 59°, as 
shown in cut No. 6. Grinding to less angle leaves the lip hooking, and 
is likely to produce a crooked and irregular hole. The grinding lines 
to a drill are placed slightly above the center, to allow for the proper 
angle of point, which is an important factor. This angle is an index 
to the clearance. If the angle is too much, the drill cuts rank; if not 
enough; the drill may not cut. Fig. 2 shows a proper angle. In Fig. 3 
the angle is too sharp. In Fig. 4 the angle runs backward, and shows 
the want of clearance. An effective method of determining the clear- 
ance is to set the point of the drill on a plane surface, holding a scale as 
shown in cut No. 5; by revolving the drill its clearance is shown, as 
well as the height of the cutting lips, which should be equal; also the 
cutting edges should be of exactly equal length, — any inequahty of 
lengths doubles itself in work. To strengthen the drill, the center is 
made thicker toward the shank. As the drill is shortened through use, 
the center shows thicker, and will work hard in drilling. To overcome 
this, the center should be thinned, care being taken to remove an equal 
amount of stock on each side, and so keep the point central. In grind- 
ing a drill preserve the original form, which usually will insure rapid 
and satisfactory work."

SUGGESTIONS FOR ORDERING REAMERS 

Regular Reamers. — Always order by catalog number. 

Special Reamers. — Refer to the catalog number for general 
style of tool required, giving also the following information : — 

Special Solid Reamers. — Give total length and length of flutes.

TO SHARPEN REAMERS 

Hand Reamers, when dull through wear, should be stoned first on 
the face of the flutes, then on top of the flutes. The stone should be 
always held perfectly flat with the face and clearance that the original 
shape of the flutes may be preserved. 

End Cutting Reamers should be first ground on centres with a 
wheel, and then recleared to insure reaming a hole the same size of 
Reamer. 

The Norton Co. make a stone which is adapted for the purpose, 
and gives quicker results than any oil stone. The stone should be 
kept clean by the use of turpentine. 

It is always understood that when orders for Special Goods are 
accepted they are not subject to cancellation.

ACME STANDARD 
29° Thread 




This Thread has been devised to take the place of the Square Thread. 
It has the same depth as the Square Thread, but is stronger, as the 
bottom of the thread is wider than the Square Thread. The sides of 
this Thread are at the same indination as is now generally adopted in 
cutting Worms. 

Taps and Dies to this Standard are made only to order, and prices 
will be given on application.

The right hand column gives the number to be subtracted from the 
diameter to obtain the caliper reading. 

The figures in above table apply only to screws made accurately to 
standard size. 

Taps are always made oversize, screws as well as taps, having the V 
Form of Thread are usually made considerably larger than the figures in 
above table.

SUGGESTIONS FOR ORDERING CUTTERS 

Regular Cutters. — Always order by catalog number giving 
diameter, face, and size of hole. 

Special Milling Cutters. — Give diameter, face, size of hole and 
keyway and refer to catalog number for style. When End Mills, 
Angular Mills. Facing Mills and T Slot Cutters are desired, be par- 
ticular to state whether Right or Left Hand. 

Formed Cutters. — Sketches showing form and all dimensions, or 
template showing form together with all dimensions, should be furnished 
when ordering Formed Cutters. Also state whether Cutter is "coming" 
or "going" at the bottom. Formed Cutters are adopted for work 
where uniformity is required, and are sharpened by grinding the faces 
of the teeth. 

Gear Cutters. — Give number of cutter and diametral pitch when 
ordering. Diametral pitch means the number of teeth to the inch in 
diameter in pitch circle of any wheel. These cutters are sharpened by 
grinding the faces of the teeth. 

To get best results be sure Cutters are Kept Sharp. 

It is always understood that when orders for SPECIAL GOODS 
are accepted they are not subject to cancellation.

Specific Gravity 

Weight per Cubic Foot 

Weight per Cubic Inch 

As there are many gauges in use diflfering from each other, and even the thicknesses 
of a certain specified gauge, as the Birmingham, are not assumed the same by all manu- 
facturers, orders for sheets and wires should always state the weight per square foot, or 
the thickness in thousandths of an inch.
